Define Task Card
Explanation
This activity is used to define a task card that can be used on
maintenance event types, i.e., interval maintenance, modifications, condition limits, faults,
life limits, and post maintenance checks.
There can be one or more revisions of a certain
task card. Each task card revision will contain information on the
work that is to be performed when serials with the defined part revision
are to be maintained. What, where, and the workload of the task card is defined
here. Resources, material,
zones, sign off requirements, task card criticality, condition
measurements, event codes the task card is to be included on, and
subtasks can be specified. At creation, the task card revision will
automatically receive the Preliminary status. When the task card
revision is in this status (or in the Active status) it will be
possible to connect the task card to event codes, such as, maintenance codes,
condition limits, modification codes, fault functions, life limits, and post
maintenance check IDs.
When the workshop receives a maintenance assignment with a distribution
type of Work Order or Execution Logic Structure, the
task cards for the part revision will be
transferred to the work order. Only
task cards in the Active status will be transferred
to work orders. The status of the
task card
revision can be changed to Active or Obsolete depending on your
requirements. This information is shown in point form in the following table:
Status |
Description |
Preliminary |
- When the task card revision is created, it
will receive this status
- Task card revisions in this status can be
connected to event codes
- Task card revisions in this status will not be distributed to work
orders
|
Active |
- When the definition of the task card
revision is complete, it can be set to this status
- Task card revisions in this status can be
connected to event codes
- Active task card revisions will be distributed to work orders
|
Obsolete |
- If the task card revision is no longer valid
and should not be used, it should be set to this status
- When a task card revision is set obsolete,
the task card will be removed from all places in which it is currently
used
- Obsolete task card revisions will not be distributed to work orders
|
Each task card is defined for the specific part revision, e.g., aircraft
engine or locomotive bogie, on which the task card is applied. The affected part revision
in the structure on which work is to be performed, for instance a pump in the
aircraft engine or a wheel on the locomotive, must be indicated. You must also
indicate where in the function structure the work is to be performed. If the
work is to be performed directly on the part revision (aircraft engine/train),
the affected part revision must be the same as the part revision.
The number of required levels in the function breakdown is managed by object
property settings. For serial parts, the valid object property is FUNCTION_LEVEL_INSTR.
For vehicle parts it is
FUNC_LEVEL_INSTR_VEH. Legal values for these settings will be 0, 1, 2 and 3.
Object properties can be found in Configuration
Basic Data/Object Property tab.
The planned duration of the task card and a description of the work to be performed
must be registered.
For each task card, you must specify where the work is to be performed by
registering one of the following field combinations:
- Template Part No, Template Part Rev, and
Structure Position indicates that the task card is performed on the
specific structure position regardless of what is installed in the
position. The List of Values displays the possible combinations that exist
in the structure of the part number and revision that are entered on the
task card.
- Affected Part No and Affected Part Rev
indicates that the task card is performed on that part number/revision
combination in all places in the structure where the combination exists. The
List of Values displays the possible combinations that exist in the
structure of the part number and revision that are entered on the
task card.
- Template Part No, Template Part Rev, Structure Position,
Affected Part No, and Affected Part Rev indicates that the
task card is performed on that specific structure position if the specific
part number and revision is installed in the structure position. The List of
Values for the Template Part No,
Template Part Rev, and
Structure Position fields display the possible combinations that
exist in the structure of the part number and revision that are entered on
the task card. The List of Values for the Affected Part No and
Affected Part Rev fields display the possible combinations that can be
installed in the given structure position (including prime part, template
alternates and position alternates).
When registering a new revision of a part that requires new task cards, it is possible to copy the
task card information from a previous
part revision and then make changes to the task card for the new part
revision. It is also possible to copy between revisions of different part
numbers to reuse the task cards on parts with the same maintenance needs.
Prerequisites
- A valid part revision must exist.
The following prerequisites depend on the values you
will enter on the task card revision:
- When defining task cards, the
template structure together with its product, model and
function structure must exist.
- Task card types, locations, strategies, and execution phases must exist.
System Effects
- The task card revision is defined.
- Resources, material, zones, sign off requirements,
criticality, and condition measurements can be entered on the task card.
- The task card can be connected to maintenance event codes.
- Subtasks can be connected to the task card revision.

Procedure
The following steps describe entering values that are
required for creating a task card. Note that the requirement for
values in the Function Breakdown area is dependent on defined object
property settings. A list of the optional values that can be defined on the
task card is described below these steps.
- Open the Task Card window and create a new record (F5).
This procedure can also be run from the Task Cards
window and the Serial Part Revision/Task
Cards tab.
- In the Part Number field, enter the part number of the desired
part. Use the List of Values to select a valid
value.
- In the Part Rev field, enter the revision of the part by
selecting a value from the List of Values.
- In the Task Card ID field, enter an identity for the task card.
- In the Revision field, enter the revision
of the task card.
- In the Description field, enter the
description of the task card.
- If the part revision for which the task card is being created is
connected to a product model, values for the Product Number and
Model Number appear automatically. If not, use
the List of Values to select a valid value.
- The fields Function Number, Sub Function, and Bottom
Function describe where in the function structure the work should be
performed. The function structure is defined for the product model.
- In the Duration field, enter the planned duration of the task
card, in hours.
- In the Work Description field, enter a description of the work to
be done on the task card.
Optional fields:
- In the Type field, enter the type of task card. Use
the List of Values to select a valid value.
- In the Location field, enter the location on
the serial where the work should be performed. Use the List of Values to
select a valid value.
- In the Exec Phase field, enter the
maintenance phase during which the task card will be performed. Use the List
of Values to select a valid value.
- In the Strategy field, enter the strategy to which this task card
belongs. Use the List of Values to select a valid value.
- If the task card is issued by a manufacturer (or similar), enter the
manufacturer's task card ID in the Ref Number field.
- In the Template Part field, enter the template part number and
revision (in the adjoining field) of the template to which the affected
structure position belongs. Use the List of Values to select a value.
- If the task card applies to one specific structure position in the template
structure, enter the ID of the position in the Structure Pos field.
If a value is entered in this field, values for the Affected Part
and Affected Part Revision must be entered.
- In the Affected Part field, enter the part number and revision
(in the adjoining field) of the affected part in the structure of the
selected part. Use the List of Values to select
a value.
Note: Creating task cards for modifications, condition limits,
maintenance codes, faults, life limits, and post maintenance checks uses a similar procedure but the
Task Cards tab is accessed from different windows (Modification Details/Execution
Type Info for
modifications, Serial Part Revision/Life Limit
for life limits,
Task Cards for Maintenance Code for maintenance codes etc).
